Bit 1

Boring CYCLE86: Take into account the rotation of the tool plane when positioning the

spindle

Note:

Spindle direction of rotation M3/ M4 and direction of rotation of the rotary axes must be set

according to DIN. For SPOS=0, the tool cutting edge points in the + direction of the 1st axis

of the plane (for G17, to X+).

= 0

Do not take into account the rotation of the tool plane when positioning the spindle (SPOS).

= 1

Take into account the rotation of the tool plane when positioning the spindle (SPOS).

Bit 2

Boring CYCLE86: When positioning the spindle, take into account swiveled table kinematics

(tool carrier)

= 0

When positioning the spindle, do not take into account the components of the swiveled table

kinematics (swiveling with CYCLE800, tool carrier).

Note:

Only the rotary axis of the machine kinematics that rotates the workpiece is taken into ac-

count. In the initial state of the kinematics, this rotary axis must be orientated parallel to the

tool axis.

e.g. rotary axis C rotation around Z (for G17) rotary axis vector of the swivel data set V2xyz

= 0 , 0 , -1.

Prerequisites for the simulation mode

Configuration

If you use feedback signals regarding the machine state, e.g. in CYCPE1MA, for tool change

cycles, measuring cycles or CUST_800, then in the NC program you must link in the following

system variables in order to avoid PLC access. Otherwise, PLC access prevents data

alignment, results in alarms or the simulation being canceled:

18.3.3

Extending the PROG_EVENT standard cycle

If you wish to extend the functionality of the PROG_EVENT, then you must not copy this into the

manufacturer cycles directory, but you must create two new manufacturer cycles. Use the

names CYCPE1MA.SPF or CYCPE_MA.SPF names for the manufacturer cycles.

For the manufacturer cycles CYCPE1MA.SPF or CYCPE_MA.SPF, the corresponding

jump markers are prepared at the beginning and at the end of PROG_EVENT.SPF.

If the CYCPE1MA.SPF and CYCPE_MA.SPF manufacturer cycles are created in the NC, the

program correspondingly branches from PROG_EVENT to the manufacturer cycles.

Procedure

Select the "Start-up" operating area.

2.

Press the "System data" softkey.

3.

Select the directory /NC data/Cycles/Manufacturer cycles

4.

Press the "New" softkey.

Software option

You require the following software option in order to use the counterspindle on your

machine:

"Generic coupling 'CP-STATIC'" or higher

The position to which the counterspindle travels when the program starts is defined in the

following channel-specific cycle setting data:

SD55232 $SCS_SUB_SPINDLE_REL_POS

Retraction position Z for counterspindle

The following channel-specific setting data becomes effective when traveling to the fixed stop:

SD55550 $SCS_TURN_FIXED_STOP_DIST

Distance for travel to fixed stop.

SD55551 $SCS_TURN_FIXED_STOP_FEED

Feedrate for travel to fixed stop.

SD55552 $SCS_TURN_FIXED_STOP_FORCE

Force for travel to fixed stop in %.

Between traveling to the fixed stop and gripping, the counterspindle can retract a short distance

to counteract compressive stress in the workpiece.

SD55553 $SCS_TURN_FIXED_STOP_RETRACTION

Retraction distance before clamping af-

ter fixed stop.

After gripping you can cut off the workpiece. Before doing so, the counterspindle can retract a

short distance with the workpiece to exert tensile stress on the workpiece. This relieves

pressure on the tool when cutting off.

SD55543 $SCS_TURN_PART_OFF_RETRACTION

Retraction distance before cut-off.

After cut-off, you can carry out a cut-off check and for turning, use the "Travel to fixed stop"

function. You can activate/deactivate the cut-off check using the channel-specific cycle setting

data:

SD55540 $SCS_TURN_PART_OFF_CTRL_DIST

Distance for cut-off check.

SD55541 $SCS_TURN_PART_OFF_CTRL_FEED

Feedrate for cut-off check.

SD55542 $SCS_TURN_PART_OFF_CTRL_FORCE

Force for cut-off check in %.

The cut-off is successful when travel to fixed stop fails. The following alarms are output:

Alarm

Alarm text

20091

Axis %1 has not reached the fixed stop.

20094

Axis %1 end stop has been aborted.

You can switch off the alarm display using the following machine data:

If, however, the specified force is reached during the cut-off check (i.e. travel to fixed stop is

successful), alarm 61255 "Error during cut-off: Tool break?" is issued.

Note

The "Travel to fixed stop" function can also be used when gripping the spindle (see above). If

travel to fixed stop does not succeed when gripping, an alarm will of course still be issued.

Instead of alarms 20091 and 20094, the alarm 61254 "Error during travel to fixed stop" will be

issued.

Note

MD37050 can also contain values not equal to 2, e.g. 10 = 2 + 8. Make sure that the value 2 is

always contained logically so that the monitoring for travel to fixed stop can be hidden. If

MD37050 does not contain the value 2, the cut-off check is not active.

Machine manufacturer cycle

If you perform one of the following actions, you must adapt the machine manufacturer cycle

CUST_TECHCYC.SPF.

● Switch between spindle and C axis mode for the main spindle or counterspindle.

● Open, close, flush chuck (main spindle / counterspindle).

● Change default settings for the coupling of the main spindle and counterspindle.

The roughing step for residual machining is not executed, if the material to be removed is less

than 50% of the finishing allowance. The material is only removed when finishing.

Example: If the SD is set to 50% and the final machining allowance is 0.5 mm, any residual material less

than 0.25 mm is not removed with the residual machining - but is removed during finishing. If during a

machining step, less residual material is present than defined in the SD, the error message "No material

present" is issued. This means that this residual material roughing step can be omitted because no

machining is performed.

SD55588 $SCS_TURN_CONT_MIN_REST_MAT_AX2

18.7.1

Technology cycles for swiveling

Requirement

The commissioning of the machine kinematics is a mandatory requirement for correct swiveling

functionality (CYCLE800). The vectors of the machine kinematics are stored in the tool

parameters $TC_CARR1 to $TC_CARR65.

Note

The vectors of the machine kinematics can be determined with the "Measure kinematics"

measuring function (CYCLE996).

To activate the swivel function, there must be at least one tool holder that can be oriented

(swivel data set) in the NCK, and the workpiece, tool and rotary table reference system frames

must be activated:

Note

If, after a RESET from the NC, a frame must be calculated in the tool direction, then

MD20150 $MC_GCODE_RESET_VALUES[52] can be set to a value > 1.

Applications:

● Machine kinematics with Hirth joint

● Angular tool with basic tool orientation

Note on kinematics (swivel head / mixed kinematics) with Hirth joint:

Depending on the active plane (G17, G18, G19), the TOROT command (or TOROTX,

TOROTY) is programmed in the NCU (G group 53) to calculate the compensating frame for the

Hirth joint in CYCLE800. If the Hirth joint causes the programmed rotation to deviate from the

possible positions of the rotary axes, a $P_TOOLFRAME compensating frame is created for

swivel head and mixed kinematics (see HMI active ZO / details tool reference).

If the compensating frame must be retained after RESET or end of part program, enter the

following value in the channel-specific machine data:

Bit 19 acts only with bit 10 = 1.

MD21186 $MC_TOCARR_ROT_OFFSET_FROM_FR

Offset of the rotary axes for an oriented

tool holder from the work offset of the ro-

tary axis.

= 0

In CYCLE800, the WCS is recalculated when there is a value in the work offset (WO) of

the rotary axes.

If values are entered in the work offset of the rotary axes of the active swivel data set,

the basic position of the swivel data set and therefore also the basic position of the WCS

can change.

= 1

A value in the ZO of the rotary axes acts as offset of the oriented tool holder. The Work

remains unchanged.

MD21186 may not be rewritten in a program with call CYCLE800.

The setting MD21186 = 0 is only suitable for a swivel data set in which one of the available

rotary axes rotates exactly around the tool axis. In this way, a useful rotation of the WCS can

be calculated in CYCLE800 when values are entered in the work offset of the rotary axes. For

example, for a swivel table with rotary axis A around X and rotary axis C around Z for a basic

position of the kinematics in G17.

If several swivel data sets are declared per channel, and if machine functions need to be

activated on changeover between swivel heads or tables, an M command can be issued in the

PLC program on switchover to another swivel data set.
